How do you boot your PSP up in recovery mode?

I have updated my PSP firmware to 3.52 M33 and im having issues playing some games (.cso file, Ghost recon to be exact) and everytime i try and run it, it just goes to a blank screen and doesnt go any further than that.

i have been told by others if i boot up in recovery mode and enable the 'no umd' option, this should solve the problem but i dont know for the life of me how to boot up in recovery mode.

Im sure its something easy and it might be a silly question, but i am stuck and i need help.

even the 007 game i was able to use on 3.40 firmware does the same thing too now.

two things possible (or maybe more)... one it is either a bad iso and you need to download it again. the no umd option has nothing to do with a black screen, it will just give u a error sign and take u back to the XMB. the next thing u can do is to go to recovery menu > advanced > advanced configuration. now enable plain modules in umd/iso and then try running it again... if that doesnt work A(for example launching ratchet and clank doesnt work for me via xmb. i got it to by ttoggling with my options but anyways... you can try running it with IR SHELL.
